Syncfusion.PDFViewer.Windows issue after deployment

Question

Currently referencing the following assemblies:

v 15.1460

Syncfusion.Compression.Base

Syncfusion.Core

Syncfusion.Pdf.Base

v 15.1400

Syncfusion.PdfViewer.Windows

I've been able to develop with no issues but after I've deployed I get the error,

Could not load file or assembly 'Syncfusion.Pdf.Base, Version=15.1400.0.33, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Any idea why it works on my vm but not after deploying? Is there a matching Syncfusion.PdfViewer.Windows that I'm missing?

Please advise. Thanks

Hi Justin, 

Thank you for contacting Syncfusion Support. 

On analyzing the details provided in the forum we found that there is mismatch in the assemblies version referred in the project. The project is referred to 4.6 .NET framework assemblies of Syncfusion.Compression.Base, Syncfusion.Core and Syncfusion.Pdf.Base  and 4.0 .NET framework assembly of Syncfusion.PdfViewer.Windows. Please update the assembly reference of the project to refer all required assemblies in the same .NET framework and version used in the project.  

Kindy try the above solution and revert us with more details if you are still facing the issue. These details will be helpful for us to investigate more on your requirement and assist you better. 

Thanks,
